Abstract
Die Erfindung betrifft eine Vorrichtung zur Aufnahme eines Hyperspektralbildes eines Untersuchungsgebietes mit
- einer Lichtquelle (3) zur Bestrahlung des Untersuchungsgebietes,
- einem Eingangsobjektiv (2) zur Erzeugung eines Bildes des Untersuchungsgebietes in einer Bildebene,
- einem Spektrometer (11), das eine in der Bildebene angeordnete schlitzförmige Blende (7) zur Selektion eines schlitzförmigen Bereichs des Bildes, ein dispersive Element (9), das so aufgebaut und angeordnet ist, dass die dispersive Auffächerung des durch die Blende hindurch tretenden Lichts in einer von der Längsrichtung der Blende verschiedenen Richtung erfolgt, und einen Kamerasensor (10) zur Aufnahme des Beugungsbildes aufweist, und
- einer Datenverarbeitungseinrichtung zur Aufnahme der Kamerasensorsignale als eine Vielzahl von Spektren mit jeweils zugeordneter Ortskoordinate x entlang der Längsrichtung X der Blende,
- wobei die Vorrichtung dazu eingerichtet ist, in einer von der Längsrichtung X verschiedenen zweiten Richtung Y aufeinanderfolgende schlitzförmige Bereiche des Bildes des Untersuchungsgebietes mit zugeordneter Ortskoordinate y aufzunehmem,
- dadurch gekennzeichnet, dass das Spektrometer (11) in der zweiten Richtung Y verfahrbar relativ zum Eingangsobjektiv (2) gelagert ist, eine Antriebseinrichtung zum gesteuerten Verfahren und Einstellen der Position des Spektrometers (11) in der zweiten Richtung Y vorhanden ist und dass die Datenverarbeitungseinrichtung dazu eingerichtet ist, das Spektrometer (11) schrittweise zu verfahren, um so sukzessive aufeinanderfolgende schlitzförmige Bereiche mit Spektren mit zugeordneten Ortskoordinaten x, y aufzunehmen und zu dem Hyperspektralbild zusammenzusetzen.
The invention relates to a device for recording a Hyperspectral image of a study area with
a light source (3) for irradiation of the examination area,
an input objective (2) for generating an image of the examination area in an image plane,
- A spectrometer (11) having a slit-shaped aperture (7) arranged in the image plane for selecting a slit-shaped region of the image, a dispersive element (9) which is constructed and arranged such that the dispersive fanning of passing through the aperture Light in a direction different from the longitudinal direction of the diaphragm, and has a camera sensor (10) for receiving the diffraction image, and
a data processing device for receiving the camera sensor signals as a multiplicity of spectrums, each with an associated spatial coordinate x along the longitudinal direction X of the diaphragm,
- wherein the device is adapted to receive in a second direction Y different from the longitudinal direction X successive slit-shaped regions of the image of the examination area with an associated spatial coordinate y,
- characterized in that the spectrometer (11) is movably mounted in the second direction Y relative to the input lens (2), a drive means for the controlled method and adjusting the position of the spectrometer (11) in the second direction Y is present and that the data processing means is arranged to move the spectrometer (11) stepwise, so as to successively record successive slit-shaped regions with spectra with associated spatial coordinates x, y and to assemble them into the hyperspectral image.
